The frequently repeated keystone lie that Europeans have equivalent or greater rights, freedoms, and protection from authoritarianism than Americans, which is and has always been objectively and completely false.

Well according to press freedom indices many European countries and the US are quite similarly ranked. Some countries better some countries worse.

Some countries have stronger institutions against dictatorships than others but unfortunately we have seen that even the US isn't immune and that slides auch as in Poland and Hungary are possible.

There is always hope that things can turn around (as in Poland even though the road is hard and there are setbacks)

Citation? Every democracy index I've ever heard of rates most of Europe as more democratic than the US. (Eastern Europe will typically be rated lower, all of the former USSR states seem to be struggling with various degrees of corruption or similar problems)

The most commonly used index for example:

Well, when fascists are in power, paper won't help anyone. But at this point, as a European I enjoy enumerated human and civil rights from multiple constitutions and several international treaties, which are directly enforceable by courts at the state, national, and European level.

The human and civil rights guaranteed by the US constitution are a complete joke in comparison, and most of them are not guaranteed directly constitution, but by Supreme Court interpretation of vague 18th century law that can change at any time.
